Hi and welcome to HCMSciatica
pain in right leg of your mother is due to prolapse disc at lumber spine causing compression over nerve roots. This sciatica pain not seems to be any co-relation with fibroids in uterus
. Pain during menses can be co-related with fibroid.
There are several treatment modalities with medicines, physiotherapy
and with injections in the back called epidural injections and root/facet blocks for disc prolapse
If she don't get better with these treatment , another option is surgery, by which the nerves are decompressed by removing the protruded disc (discectomy
), which would significantly improve her symptoms.
Hope this will helps you. Take care.
